The object of this invention is to simplify and cheapen the constructionof thrashing-machines, and also to render them readily adapta ble todifferent kinds of grain.

The accompanying drawing is a vertical longitudinal section of myimproved machine, designed to illustrate my invention.

A designates the thrashing drum or beater; B,the concave or breasting,and C an inclined chute or chute-board hung beneath the breasting. I) isthe straw-shaker, and I the frame thereof.

E is the caving riddle or riddles, and K the flame or shoe thereof. Theriddle E or its shoe K is suspended by four hangers, H H, one at eachcorner, (but two of which are shown,) so that it is free to reciprocatein a direction longitudinally of the machine. It is so reciprocated bymeans of a crank, G, and pitman F,

as usual. There should be two cranks and pitmen at opposite sides of themachine. The front end or portion of the straw-shaker D or its frame Iis mounted on and fixed to the shoe K, straps X X being preferably usedfor connecting them. By this means both strawshaker and caving-riddlesare reciprocated -together and by the same mechanism, instead of beinghung and moved independently, as most commonlyheretofore constructed.The strawshaker D is formed with a hinge or j oint, L, near its frontend, so that the portion to the rear of this joint may be raised orlowered independently of the portion to the front thereof. This jointmay be placed somewhat forward or back not subject to undue vibration.

of the position shown, or even at the extreme riddle on which it ismounted. The rear end of the shaker is supported from the cavingriddleby any suitable adjustable connection, but preferably by a screw, M, andnut N, as shown, so that 'by rotating this screw in the nut theinclination of the shaker may be easily and accurately adjusted.

The'chute-board O is suspended by four hangers, H H, two of which engageits right and left rear corners, while in the construction shown theother two engage the front corners of a shoe, (1, to which the chute isfixed rigidly. This shoe is in a distinct compartment of the casing ofthe machine, separated from the main or thrashing compartment by apartition, I), and the chute 0 passes freelythrough an opening in thispartition. The ob ject of this construction, which forms 110" part of mypresent invention, is to utilize one set of hangers and onereciprocating crank and pitman for hanging and reciprocating both thechute G and shoe (1.

A crank, G, is formed on the crank shaft, with its throw to the oppositeside from that of the crank G, and a pitman, F, connects this crank withthe chute C, by which means the chute and shoe (4 are reciprocatedcoincidently with and in opposite directions from the caving-riddleE-that is to say, the chute and riddle move alternately toward and fromeach other, so that, being approximately of equal weight, each sustainsthe thrust of the .reciprocations of the other, so that the frame of themachine is relieved from strain, and is The chute C is so arranged thatit receives the grain and cavings or short straws which fall through thebreasting B, and, by being inclined backwardly, conducts them onto thecaving-riddle E. The straw discharged by the beater A is thrown onto thestraw shaker D, where it is agitated and travels to the rear end of themachine, whence it is discharged. The grain that is carried onto theshaker with it is disengaged by its agitation, and falls through theshaker onto the caving riddle E or onto a chute, cl, which carries itforward, and finally drops it on this riddle. The caving-riddle inclinesto'the rear,'and by its agitation the cavings are delivered at the rearof the machine, while the grain drops through onto a chute, e, whichconveys it to a screen or riddle, f, whence it falls on another chute,g, which delivers it onto a series of screens,-h, h. After falling fromchute e, and before reaching screens h h, the grain is subjected to acurrent of air from a fan, i, which blows out the chaff. This portion ofthe apparatus constitutes a first cleaning or winnowing mechanism, suchas is common to thrashers. The chutes e and g and the screens f and h hare all mounted in a downward continuation of the shoe K, andreciprocate with the caving-riddle E.

From the screens h h the grain is conducted to an elevator, j, by whichit is carried through an inclined trunk, 70, (shown in dotted lines,) tothe top of the compartment in which is the shoe a. This shoe containsthe screens of a second cleaning or winnowing apparatus, receiving airfrom a fan, on, by which apparatus the grain is finally cleaned and theseveral grades are assorted and deposited in separate receptacles. For amore complete description and illustration of this second cleaning andassorting apparatus, reference is made to my application No. 71, 241,filed simultaneously herewith.

I claim as my invention- 1.v The combination, ina thrashing-machine, ofcaving-riddle E, shoe K thereof, crank G and pitman F, for reciprocatingsaid shoe and riddle, straw-shaker D, mounted on said shoe above saidriddle, so as to necessarily reciprocate therewith, a joint, L, at ornear the front end of said shaker, whereby the portion of said shaker tothe rear of said joint may be inclinedto difierent angles, and anadjustable support interposed between the rear end or portion of saidshaker and the shoe, whereby the shaker may be set at any desiredinclination, substantially as set forth.

2. The combination, in a thrashing-machine, of the'thra'shing-drum A,breasting B, reciprocating chute 0, arranged thereunder, cavingriddle E,arranged with its higher end beneath the delivering end of said chuteand its lower end remote therefrom, suitable means for reciprocatingsaid chute and riddle simultaneously in opposite directions, and thestrawshaker D, arranged above said chute and be yond the thrashing-drum,and mounted above and fixed to the caving-riddle, so as to recip rocatetherewith, substantially as set forth.

3. The combination ofcaving-riddle E, means for reciprocating it, thestraw-shaker D, mounted upon and above said riddle, and with its rearend fixed thereto, a hinge or joint in said shaker near or at its rearend, and means for raising or lowering its front end relatively to saidriddle, whereby the inclination of the straw-shaker may be adjustedwithout changing the inclination of the riddle, while both re= ciprocatetogether, substantially as set forth.

4. In a thrashing-machine, the combination of the cavingriddle E, shoeK, and straw shaker D, all suspended by hangers H H, joint In in saidstraw-shaker, and screw M and nut N, for adjusting the inclinationthereof relatively to the oaving-riddle, substantially as set forth.

In witness whereof I have hereunto signed my name in the presence of twosubscribing witnesses. ALFRED \VILLIAM HANTLE.
